If you want to be ripped by summer I suggest you start now! Losing fat the right way is losing it slowly at a pace of 1-2 lbs a week so you don't lose muscle while losing weight. Also, cardio 30 min 3 times a week and weight lifting 4-5 times a week is perfect for a natural bodybuilder. Also, diet must be in a 250-500 cal deficit each day to see consistant results.
So get started now so you can enjoy the summer later!
